Reborn on the day of her coming-of-age ceremony, Murong Wan refuses to endure humiliation any longer. Whoever dares lay a hand on her will get slapped in return. Her cousin Qin Yue'er appears gentle and kind, but secretly tests her at every turn, while her half-sister and concubine stepmother plot against her behind her back. Murong Wan counters every move and exposes their schemes one by one. She forms an alliance with the Ninth Prince, Nangong Su, who seems carefree and idle but is actually hiding extraordinary depths. One manages the household accounts while the other establishes secret networks throughout the capital, working together amid business scandals and political turmoil. After her father leaves for war, Murong Wan is left to shoulder the entire burden of the Marquis's household alone. Pressure to enter a political marriage, mysteries surrounding her birth, and the lingering fallout from the money house scandal come crashing down one after another. In this life, she will neither hide nor endure. Everyone who owes her will repay every debt, one by one.
